Install Instructions For Hearthstone H-I Glass (12" × 6"): 91-58105-AMP
1.) Remove the front/door. To remove, open the front door and tap out the hinge pins using a hammer and a small punch. Tap the hinge pins up from the bottom of each hinge tab on the door frame. Lay the door face down on a protected surface (i.e., cardboard, a heavy blanket).
2.) Apply penetrating oil to the screws holding the glass retention bars in place and allow them to set for a few minutes (Note: Before handling the damaged glass, be sure to put on your work gloves and safety glasses).
3.) Remove the screws holding the glass retention bars in place with the 5/16” wrench (Note the placement of each of the bolts. Occasionally oversized bolts were used in the assembly of the stove). After the retention bars are removed, carefully lift out the damaged glass and discard it.
4.) Pull the paper backing off the new flat gasket. The adhesive side is applied to the glass overlapping each side. Continue around the glass until the entire glass is wrapped with the tape and cut off any excess.
5. Place the glass panels back into the doors. Lay the retention straps back into place and secure them with the screws.
6. Place the doors back onto the stove and tap the hinge pins back into place.
